• Create a certificate signing request (see here)
• Create a iOS Distribution (App Store Connect and Ad Hoc) (same as these instructions but select the different type on step 3)
• Download the certificate (must be done upon creation and will be called ios_distribution.cer)
• Import into login section of Keychain Access (must be launched with spotlight because it doesn't show up in Launchpad)
• Select My Certificates and then export the certificate as a .p12 (it will prompt for a password)
• Copy the .p12 in base64 format ( base64 -i ios_distribution.p12 | pbcopy )
• Add it as a secret called APPSTORE_CERTIFICATES_FILE_BASE64 and the password as APPSTORE_CERTIFICATES_PASSWORD

uses: apple-actions/import-codesign-certs@v3
with: 
  p12-file-base64: ${{ secrets.APPSTORE_CERTIFICATES_FILE_BASE64 }}
  p12-password: ${{ secrets.APPSTORE_CERTIFICATES_PASSWORD }}

If you need to add multiple certificates, select them all in the keychain when creating your p12 file. You do not need multiple separate steps.

See action.yml for more details.
